FURNITUREGLA1VIB To all fwhom t may concern:

Be it known that I, DAVID S. AonLnv, a citizen of the United States ofAmerica, residing at Grand Rapids, in the county of Kent and State ofMichigan, have invented certain new and useful Improvements in Furniture-Clamps; and 1 do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to improvements in furniture clamps and moreparticularly to clamps adapted to be used in assembling drawers forfurniture, and its object is to provide convenient means for clampingdrawers and other like articles of various sizes and shapes, and toprovide the same with various new and useful features, hereinafter morefully described and particularly pointed out in the claims.

My invention consists essentially of two hollow posts verticallyarranged upon a suitable bed, and adjustable thereon toward and fromeach other, screw clamps pivoted in the said posts and adapted to engagethe work either vertically or-` horizontally, and various adjustablesupports and clamping members mounted on the said posts, 'as will morefully appear by reference to the accompanying drawings, in which:

Figure 1 is a side elevation of the device embodying my invention; Fig.2 a longitudinal vertical section of the same somewhat enlarged; Fig. 3a plan view of the same broken away do-wn to line 3 8 of Fig. 2; Fig. aan elevation of one of the posts and parts attached; Fig. 5 an elevationshowing the middle clamp; and, Fig. 6 a plan view of one of the postsand parts attached shown in horizontal section with the upper partremoved.

Like numbers refer to like parts in all of the figures.

1 represents the bed of the machine of any convenient or preferreddimensions, provided with ways 2 on which are slidably mounted hollowsemi-cylindrical posts 3 and t, these posts being each provided on theplane side with vertically disposed ways 9. In each post is mountedavertically disposed screw 10 pivoted at its lower end in a transverserack shaft 11 and having thereon a vertically adjustable clamp member 12having aninwardly lprojecting portion, which when the respective screwis adjusted sub- Specieation of Letters Patent.

' stantially vertical, projects inward sufficient to engage the uppercorner of a drawer or other similar structure, and when the screws areinclined away from each other, these members engage a face of the ways 9and present vertical surfaces adapted to horizontally clamp the same,thus being adapted for use in either relation, as occasion requires.This horizontal movement of the members 12 also facilitates placing thework in the machine or removing the same therefrom, requiring but littlemovement oit' a post to horizontally engage or disengage the. clamp withthe work. On the *ays 9 arc also mounted vertically adjustable crossbars 13 to engage the ends of the work, each bar being provided with aback stop 15 to vertically adjust the back side of the work. Other crossbars la are also provided having back stops 16. and in conjunction withthese last named bars, supporting members 17 are provided to engage thelower corners of a drawer or other like structure having a convex orswell front.

For long drawers or other like articles, a middle clamp is sometimesused consisting of a transverse bed plate 18 adjustable on the ways 2,in which is mounted a vertically adjustable bar 19 by means of a pin 22adjustable in holes 23 in the bar and extending through the plate 18. 1nthe upper end of this bar 19 is mounted a screw 21 operating avertically movable clamp 20 to engage the top or back of the drawer, andclamp the same between itself and the bed 1S. To apply pressurelongitudinally of the work and adjust the device to the length of thesame, the post 3 is adjustable step by step by means Iof a pawl 5thereon engaging ratchets 6 in the bed 1, and the post 4: is adjustedtoward and from the other post by a screw 7 manually ope 'ated by awheel 8.

I thus provide a convenient device for longitudinally and transverselyclamping a great variety of shapes and sizes of drawers or other likearticles, and one that securely holds the same in proper shape, asoccasion requires.

That I claim is 1. A clamp, comprising a bed, vertical posts adjustableon the bed, lower clamping members adapted to engage the work bothvertically and horizontally, and upper clamping members movable relativeto the posts to a position opposite the lower clamping members to clampthe work vertically,

and movable away from opposite the same to release the work.

2. A clamp, comprising a bed, vertical posts adjustable on the bed,lower clamping` members having vertical and horizontal faces torespectively engage the work, an upper clamping member having a verticalface and a horizontal face to alternately engage the work, means forshifting the upper member with its horizontal face opposite the same ofthe lower member, and means for vertically adjusting the upper clampingmember.

3. A clamp, comprising a bed, vertically disposed posts adjustable onthe bed, means for adjusting the posts, a vertically disposed screw ineach post and pivoted thereto at its lower end, clamping members mountedon the screws and adjustable both vertically and horizontally thereby,and lower clamping members adapted to co-act horizontally with themembers on the screws, and to oppose the same vertically.

et. A clamp, comprising a bed, vertically disposed posts adjustablehorizontally on the bed, means for adjusting the posts, verticallydisposed screws in the posts and pivoted thereto at the lower end,clamping members mounted on the screws and adapted to vertically orhorizontally engage the work, and transverse bars on the posts belowsaid members.

5. A clamp, comprising vertically disposed posts adjustable toward andfrom each other, means for adjusting the same, vertical ways on theadjacent sides of the posts, cross bars adjustable on the ways,vertically adjustable clamp members on the posts, and back stops on thebars.

6. A clamp, comprising vertically disposed posts adjustable toward andfrom each other, means for adjusting the posts, vertical ways on theadjacent sides of the posts, cross bars vertically adjustable on theways, back stops horizontally adjustable on the cross bars, verticalscrews in the posts, and vertical adjusting clamping members on thescrews.

7. A clamp, comprising vertically disposed posts adjustable toward andawa-y from each other, means for adjusting the posts, vertical ways onthe adjacent sides of the posts, cross bars adjustable on the ways,supporting members at the base of the supports, vertically disposedscrews in the posts, and clamping members opposite the supportingmembers and vertically adjusted by the screws.

8. A clamp, comprising vertically disposed hollow semi-cylindrical postsadjustable toward and from each other, means for adjusting the posts,vertical ways on the adjacent faces of the posts,4 adjustable cross barson said ways, back supports adjustable on the bars, vertically disposedscrews in the posts, rock shafts in the posts in which the screws arepivoted, clamp members movable both horizontally and vertically mountedon the screws and adjusted thereby, and supporting members at the baseof the posts opposite said clamping members.

9. A clamp, comprising vertically dis posed posts adjustable toward andfrom each other, means for adjusting the posts, clamping means mountedon the posts, a bed on which the posts are mounted, a transverse bedplate on the bed, a vertically adjust-able bar in the said plate, ascrew mounted on the bar, and a clamping member on the screw.

10. A clamp, consisting of a bed having horizontal ways and a ratchet,hollow semicylindrical posts adjustable on the ways, a pawl on one postengaging the ratchet, a screw mounted on the bed and engaging the otherpost, a rock shaft in each post, a screw mounted in each rock shaft, aclamp member adjustable both vertically and horizontally by therespective screws, a supporting. member on each post opposite the clampmember, cross bars on the posts, and back stops on the cross bars.

In testimony whereof I aiiiX my signature in presence ofl two witnesses.
